H9. Positive Contrast Ventriculography

Filling patterns in contrast ventriculography.

The filling patterns of a negative contrast material (air), a positive contrast water soluble material (Conray), and a positive contrast water insoluble material (Myodil) were examined in 60 normal ventriculograms. Using a scoring system developed for this study, Conray was found effective for outlining the ipsilateral (injected) lateral ventricle, the third ventricle, the aqueduct of Sylvius, ...

What is the contrast-filled structure seen during right ventriculography?

Positive contrast cerebral ventriculography using water-soluble media. Clinical evaluation of 102 procedures using methyglucamine iothalamate 60 per cent.

This chapter argues that current problem-solving models of writing fail to capture the role writing has in constituting thought. It sketches a model of language production as a knowledge-constituting process, in which content can be generated by constraint satisfaction within a distributed semantic memory, and in which sequences of ideas can be produced by inhibitory feedback from preceding out...

Cardiac Ventriculography

Cardiac ventriculography is used to define the anatomy and function of the ventricles and related structures in patients with congenital, valvular, coronary, and myopathic heart disease (1–5). Specifically, left ventriculography may provide valuable information about global and segmental left ventricular function, mitral valvular incompetence, and the presence, location, and severity of a numbe...
